Abstract:
Methods, apparatuses, systems, and devices are described for redundancy management for a storage system including a plurality of storage devices. Approaches for redundancy management may involve storage device failure prediction techniques and/or a redundancy value associated with a data file. In one example, a copy of the file may be stored on at least two storage devices. Whether or not to store an additional copy of the file on another storage device may be based at least in part on the redundancy value for the file. In another example, a determination may be made whether to store a copy of the file on another storage device when a storage device storing a copy of the file is predicted to fail. Whether to store a copy of the file on another storage device may be based at least in part on a redundancy value associated with the file.
